Which way would you go? My NP127is has the feathertouch focuser. I can add the feathertouch motor and go.. Or is the FLI focuser the way to go for repeatability and remote operation? I take it the FLI's are absolute focusers while the feathertouch is not?

Only 7mm of travel with the PDF. You can forget visual if you go this route--it assumes a custom spacer to get your camera at the right distance. It is really aimed at dedicated astro graphs. That being said, it won't flex under quite heavy loads and is repeatable.

I have noticed repeatability to be an issue. If I go from an L to an Ha, and back and forth and back and forth, focus will change. That micron focus change, over time, becomes a larger error.. Like PE!

Hopefully my indicator will be here soon and I can get back to the drawing board of getting my backlash setup correctly. Eyeballing the focus change is a PETA..
